Iran reopened its airspace after a near-five-hour closure amid concerns about possible military action between the US and Iran ‍that forced airlines to cancel, reroute or delay some flights.

Axar.az reports, citing Reuters, Iran closed its airspace to all flights except international ones to and from Iran with official permission at 5:15 p.m. ET (2215 GMT) on Wednesday, according to a notice on the US Federal Aviation Administration website.

The notice was removed shortly before 10 p.m. ET, or 0300 GMT, according to tracking service Flightradar24, which showed five flights from Iranian carriers Mahan Air, ⁠Yazd Airways and AVA Airlines were among the first to resume over the country.

At a similar time last week to the airspace closure there had been dozens of planes in the air over Iran, Flightradar24 said.
